Did I do these temp conversions right

[jim1174]

Could you please check these and tell my if i did any of them wrong? thanks Convert Degrees Fahrenheit to Degrees Celsius
72 °F = 22.2222 °C
2140 °F = 1171.11 °C
-292 °F = -180 °C
650 °F =343.333 °C
32 °F =0 °C

Convert Degrees Celsius to Degrees Fahrenheit
28 °C = 82.4 °F
950 °C = 1742 °F
-60 °C = -76 °F
100 °C = 212 °F
0 °C = 32 °F

Convert the following temperature measurements.
From To To To
0° F -17.7778 _______° C 255.222_______° K 459.3996_______° R
